Be'iii l'ifioivn tha t I, DANIEL I. Co-wGiLL, a

citizen of the United States of America, residing at Lexington in the county of Fayette and State of Kentucky, have invented certain new and useful Improvements in Metallic Railrbad-Ties, of which the following-is a specification, reference being had therein to the accompanying drawing.

' This invention relates to metallic railroad ties and has for its object the production of a simple and efficient tie which may conveniently support a rail and hold the rail insuch a position as to prevent the same from being accidentally detached therefrom and also prevent the rails from spreading.

Another object of this invention is the production of an eflicient railroad tie of metal construction which consists of a minimum number of arts.

With these an other objects in view this invention consists of certain novel combinations', constructions, and arrangements of will be hereinafter fully described and claimed.

In the accompanying drawings Figure '1 is a side elevation of the railroad tie.

Fig. 2 is a tie.

2. ig. 6 is a bottom plan view of one end of the railroad tie.

Fig. 7 is a perspective view of the top ofone end of the tie.

Fig. 8 is an inverted perspective view of one of the rail retaining plates.

Fig. 9 is a perspective view of one of the closure plates adapted to be carried by the side of'one of the railroad ties.

Fig. 10 is an enlarged longitudinal section through the bottom of the tie showing the cleats formed upon the bottom face thereof,

By referring to the drawings it will be seen that 1 designates the body of the tie which comprises a rectangular hollow structure, preferably being formed of metal. The body 1 is provided with a plurality of transversely extending cleats 2 upon the bottom face thereof, preferably T-shape in cross section, which cleats are adapted to gllp the of the "tie against lateral movement with respect to the roadbed. 1

The b dy 1 is provided near each end'with an aperture 3 upon each side of the body, which apertures are closed by means of the pivot-ally mounted gates or closure plates 4.

These closure plates 4 are adapted to nor-' mally closethe openings 3 to prevent the entrance of ballast or other foreign. sub stance to the interior of the tie. By means of the apertures 3 it willbe seen that access may be easily had to the interior of the body to facilitate the fastening of the rail retaining )lates in engagement with the body as will e hereinafter more fully described.

The body 1 of the tie is provided intermediate the ends thereof'with the upwardly projecting or raised portion 5, the end-s'yoii which raised portion 5 constitute shoulder 6 fo abutting'against the ends of the inner" rail retaining plates 7.

, Each rail retaining fiat body having a tapering rail engaging lip 8 at one end. A plurality ofspjaced'im tegral ribs 9 are formed upon the lower face of each rail retaining plate 7 and these ribs 9 are each provided with an inclined face 10 to facilitate the placing ofthe plate 7 in its proper position upon the tie 1. A pluralit of transversely extending sockets 11 are OIIIlQdJlPOIl the upper face of the body 1 of the tie for the purpose of receivin the ribs 9 formed upon the lower face 0 the rail retaining plate 7.

Each of the rails 12 is engaged upon the outer side thereof by means of a rail retaining plate 13. Each rail retainin plate 13 is provided with a plurality of ri s 14 similar to the ribs 9, which ribs fit in the sockets 15 formed upon the upper face of the tie 1.

Thetie 1 is provided upon the under face of theto thereof with a plurality of reinforcing ongitudinally extending ribs 16 formed near each end thereof and adapted to be formed, directly under the rail seat 17 formed in the body 1 of thetie.

The rail retainlng plates 7 and 13 are firmly held in engagement with the tie by means of the vertically extending bolts 18, which bolts extend through "the ribs 16, body 1 and through the respective plates 13 and 7. These bolts carry nuts 19 for the urpose of pllowing the rail retaining plates and 13 .to be easily pr readily detached from thgbody of the railroad tie. 1

mammals ballasttlf theroanberf afid'htfld at liddly l plate 7 comprises a It should be understood that the transversely extendin cleats 2 may be formed integral with the ody 1 as indicated by the numeral2 in Fi 1 without departing from the spirit of the invention. As clearly illustrated in Fig. 4 it will be seen that the top of the tie or body 1 is thickened as indicated by the numeral 20 just below the rail seat 17 to add additional strength to the tie below the point where the rails are supported thereby It will be noted by referring to Figs. -l and 7, that the openings 18 through which the bolts 18 project, extend through the body of the tie atpoints between the transversely extending sockets 11 and 15 of the tie body 1. 'lluareforc, the bolts will have a broader reinforcing surface in passing through the tie body 1, and thus the bolts will be held. from bending and will retain the rail plates more easily. Furthermore, since the bolts do not project through the ribs of the rail plates, these ribs are not weakened, but being of solid construction, without bolt openings will positively hold the rail plates in a set position. It should further be noted that the longitudinal ribs 16 formed upon the rail body 1, have bulged portions 16 so as to provide 'suflicient space for the openings 18 through which the bolts extend. In this way the longitudinal ribs will reinforce the portions of the tie body 1 upon which the rails are supported and at the same time the ribs 16 are light and inexpensive in operation and construction, while by being bulged at 16 the ribs will be held from splitting or tearing when the bolt openings 18 are termed therethrough or while the bolts are in operatism and project through the bolt opening; 1;

Having thus d ais claimed as n ce 59 In a metallic railroad tie, the combination of a tie body, said body having extending sockets formed in its upper surface, each socket being spaced at a distance from its ad'acent sockets, thereby forming bearing sur aces between said sockets, elonated longitudinally extending spaced ribs ormed integrally upon the under surface of; said tie body, said ribs being formed in planes crossing and below the planes of said soekets, whereby said body will be reinforced Where the greatest strain is brought to hear th' reon, saidribs having bulged portions adfacent their ends, said bulged ends and said tie body harin bolt openings projecting vertically therethrough, the upper ends of said bolt openings communicating with said bearing surfaces between said sockets, tie plates having spaced ribs formed thereon, said plates having bolt openings formed therethrough between said ribs, said ribs fitting within said sockets, and bolts extend; ing through said bolt openings, whereb said plates will fit uponsaid tie body an said bolts will be reinforced.

In testimony whereof I hereunto aflix my signature in presence of two witnesses.
